Available sizes are defined in the bolt assembly catalog.

Bolt standard

Bolt standard to be used inside the component.

Available standards are defined in the bolt assembly catalog.

Tolerance

Gap between the bolt and the hole.

Thread in mat

Defines whether the thread may be within the bolted parts when bolts are used with a shaft.

Slotted holes

You can define slotted, oversized, or tapped holes.

Option

Description

Default

1

Vertical dimension of slotted hole.

0, which results in a round hole.

2

Horizontal dimension of slotted hole, or allowance for oversized holes.

0, which results in a round hole.

Hole type

Slotted creates slotted holes.

Oversized creates oversized or tapped holes.

No hole does not create holes.

Rotate Slots

When the hole type is Slotted, this option rotates the slotted holes.

Slots in

Part(s) in which slotted holes are created. The options depend on the component in question.

Bolt assembly

The selected check boxes define which component objects (bolt, washers, and nuts) are used in the bolt assembly.

If you want to create a hole only, clear all the check boxes.

To modify the bolt assembly in an existing component, select the Effect in modify check box and click Modify.

Bolt length increase

Define how much the bolt length is increased. Use this option when, for example, painting requires the bolt length to be increased.

Notch tab

Use the Notch tab to automatically create notches for the secondary beams and to control the notch properties. The Notch tab has two sections: automatic properties (top section) and manual properties (bottom section). Automatic and manual notching properties work independently from each other.

Automatic notching

Automatic notching options affect both the top and the bottom flange.

Notch shape

Automatic notching is switched on when you select a notch shape.

Option

AutoDefaults can change this option.

Notch dimensions are not rounded.

Notch dimensions are rounded.

Enter the horizontal and vertical rounding values.

The dimensions are rounded up the nearest multiple of the value you enter. For example, if the actual dimension is 51 and you enter a round-up value of 10, the dimension is rounded up to 60.

Creates the notch with a line chamfer.

The notch is chamfered according to the radius you enter.

Enter a radius for the chamfer.

Manual notching

Use manual notching when a part that does not belong to the connection clashes with the secondary beam. When you use manual notching, the connection creates cuts using the values you enter in the fields on the Notch tab. You can use different values for the top and the bottom flange.

Side of flange notch

The side of flange notch defines on which side of the beam the notches are created.

Option

Description

Default

Creates notches on both sides of the flange.

Flange notch shape

The flange notch shape defines the notch shape in the beam flange.

Option

Description

Default

The entire flange of the secondary beam is cut as far back as you define.

AutoDefaults can change this option.

Automatic

The entire flange of the secondary beam is cut as far back as you define. The default depth for the notch is twice the thickness of the secondary flange. The cut always runs the entire width of the secondary flange.

Creates chamfers in the flange.

If you do not enter a horizontal dimension, a chamfer of 45 degrees is created.

Creates cuts to the flange with default values unless you enter values in the fields 1and 2.

The flange is not cut.

Creates cuts to the flange according to the value in the field 1 to make it flush with the web.

Creates cuts to the flange according to the values in the fields 1 and 2.
